SPRINKLING DEVICE.

Speccatoniof Letters Patent.

Patented Feb. 15, 1921.

Application led August 12, 1918.V SerialL No. 249,705.

To aZZwLom #may concern Be it known that l, EDWIN E. THOMAS, a citizen of the United States, residing in the city of Portland, county of Multnomah, and Sta-te of Oregon, have invented certain new and useful Improvements in Sprinkling Devices, of which the following is a. specification.

My invention relates to sprinkling devices, and more particularly to a sprinkling device having a moving discharge element adapted to travel completelyaround its axis of rotation, at various angles of adjustment above or below the horizontal, or to move in a rotary oscillating manner for different distances less than a complete rotation, with means for-automatically causing a change of the direction of movement at predetermined limits. I accomplish this change of direction by providing in the discharge member of a sprinkling device a movable detlector element positioned in thel path of the discharged water, with engaging members set at the desired limits of movement and adapted to engage said deflector element and to shift the same, whereby the action of the water thereon causes said discharge member to move in the opposite direction. I prefer to provide adjustable engaging members, whereby different distances of travel can be provided,as desired, and also different angles of adjustment above or below the hori zontal can be adopted for the discharge member. j

Another obj ect of the invention is to provide in the rotating bearing of a sprinkling device a balanced water action on the rotating member, whereby to avoid increased friction caused by the water pressure against the rotating member in one' direction only.

Other objects and advantages of myimproved sprinkling device will be apparent from the following description of one practical embodiment thereof, shown on the accompanying drawings for purposes of illustration. In the drawings- Figure 1 is a rear elevation of my invention;

Fig. 2 is a top plan view thereof;

Fig. 3 is a detail sectional view through the body of the device;

Fig. 4- is a bottom plan view of the body, partly in section;

Ving passageways, 17 and 18, therethrough Fig. 5 is a detailed sectional view of the deflector element;

Fig. 6 is a` detail showing the detlector member, partly in section. Referring now more in detail to the drawings, 1 designates a. body member, provided with means at 2 for attaching a hose thereto, said body member being hollowed, as at 3. Legs 1a, 1a of any desired length can be attached to the body member, as indicated. These are preferably detachable, whereby the device can be packed in a comparatively small package for shipment.

Rotatably mounted through said body is a short pipe section et, provided with holes` 5, 5, therethrough, within the hollowed body 1. T he lower end of said pipe section 4 is closed, preferably by means of a cap 6, secured thereto, as here shown, by means of a pin 7. Upon the upper end of said pipe section 4, is an elbow 8, above the body 1, and turning with the pipe section 4. (loir nected to said elbow to swivel therewith is a swinging neck 9, which can be turned to different adjusted positions up or down and secured by means of a set screw l0.

A djustlably secured to the body member 1, at opposite sides thereof, are two engaging members 11 and 12, adjustable about vertical axes, as by meansl of thumb screws 13, 13, and about horizontal axes, as by means of thumb.. screws 14, 1K1-, for the purposes hereinafter again referred to.

Mounted upon the outer end of the neck i), is a discharge element, 15, through which the water passes in a stream. ldovably mounted in said discharge element 15 is a deflector element, 16, provided with divergadapted to be moved into and out of regisa ter with thestream of water passing throughy said discharge element 15. Said deflector member 16, as here shown, is provided with` a slot lavthrough which is astop pin 19, to limit the movement of said deflector in opposite directions. Said deiiector 1G, it will be seen, projects through the opposite sides of the discharge member 15, in such a mannery that its opposite ends will engage the engaging members, 11 and 12, as said discharge member moves to either of them. These engaging members move the deflector 16 in the discharge member 15, from one position to the other and so as to bring the passageways 17 and 18', alternately into register with the stream of water, thus causing the dischargemember to be moved by the force of the water to the opposite engaging member. Thus by shifting the deflector element from one side to the other, the force of the water acts on said delector in such a way as to change the direction of movement oi the discharge member 15, and its carrying neck 9. This is done automatically as the delector engages one or the other of the engaging members 11 or 12.

If the engaging members 11 and 12 are dropped down out of the way, the'discharge member will then be free te rotate about its axis continuously under the force of the water. These engaging members can be so adjusted that the discharge member will oscillate through just a hall'.l rotation, or less, or more, thus making it possible to pick up Vthe sprinkler from behind while the water is being thrown therefrom without getting wet.

Attention is called to the fact that as the water enters the body 1, and the pipe section l, therein, the pressure up andl down is the same,`thus providing a balanced constructionand eliminating the friction which would otherwise be` caused by the water pressure.Y

While I have shown and described one practical form or' my invention for illustrative purposes, I am aware that changes can be made inthe details thereofwithout departing from the spirit thereoi, and I do not, therefore, limit the invention to the particular showing made, Vexcept as I may be limited by the hereto appended claims.

vI claim:

1. In a sprinkling device, a discharge element ywith discharge passageway therethrough, means for directing water through said discharge element, said means being adjustable'about a horizontal axis and turning about a vertical axis, a deflecting member movably `mounted Vin said discharge element and across the passageway therethrough, and means for automatically shifting said deflecting member, substantially .as described.

2. In a sprinkling device, a supporting member adapted to have attached thereto a source of water under pressure, a tubular member mounted therein to :turnl about a vertical axis and having arportion adjustable Vabout .a horizontal axis, a discharge element mounted on the free end of said tubular member, a deliecting element movably mounted in said discharge element, across the passageway therethrough and adapted to engage with the water passing therethrough in either of two positions, and means for automatically engaging and shifting said deecting element intermittently in opposite directions, substantially as described.

3. In a sprinkling device, a discharge element with discharge passageway therethrough, means for directing water through said discharge element, said means being adjustable about a horizontal axis and turning about a vertical axis, a deiiecting element movably mounted in said discharge element and across the passageway therethrough, and operating members adjustably mounted in the path of travel of said discharge element and adapted to engage said deiiecting element for alternately moving the same in opposite directions, substantially as described.

4r. In a sprinkling device, a body having a chamber therein, means for attaching a water supply thereto, a tubular member rotatably mounted in saidbody and having openings through its sides within said chamber, means closing the lower end of said tubular member, whereby water pressure therein is balanced in opposite directions vertically, a discharge element adjust-V tubular member rotatably mounted in said body and adjustable at its joint about a horizontal axis, means for supplying water thereto, a discharge element carried at the end of said tubular memberV and moving bodily therewith, a deiiecting member mov ably mounted in said discharge element across the discharge opening therein, and means at opposite sides of said device for alternately engaging the opposite ends or' said deflecting member for alternately moving the same in opposite directions in said discharge element, substantially7 as and for the purpose indicated. 1
